Snarling Dogs wah + Godlyke powerall == OK?

I picked up a Snarling Dogs wah, and it requires a pos tip 250mA regulated supply. Isn't this a plain regulated b0ss spec? Can I use my powerall to power this? anyone with Snarling Dogs experience? They say it is important to use their wall wart, but many manufacturers say this. What is everyone using to power SD FX?
